White surface scum on top of tank

ever since i started dosing EI i have had this very hazy/white surface layer on the top of my tank. I have tons of surface agitation from my HOB filter that runs 24/7 so i dont think this goes away with surface agitation.

I am doing macros and micros + 1.5ml iron every other day

I have a 15 gallon tank

I read online that the white surface scum could be caused by lots of iron, but it was only from one source and cant really find much about the cause anywhere else.

Can anyone provide any insight on this problem? thanks!
